Abstract

Provided are: an ion conductive solid which has high ion conductivity and can be produced by a heat treatment at a low temperature; and an all-solid-state battery having the same. Provided are: an ion conductive solid containing an oxide represented by general formula Li6−y−zY1−x−y−zMxZryCezB3O9; and an all-solid-state battery having at least a positive electrode, a negative electrode, and an electrolyte, wherein at least one selected from the group consisting of the positive electrode, the negative electrode, and the electrolyte includes said ion conductive solid. (In the formula, M is at least one element selected from the group consisting of La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. Moreover, x satisfies 0.005≤x≤0.800, y satisfies 0.000≤y≤0.400, z satisfies 0.000≤z≤0.400, and x, y, and z are real numbers satisfying 0.005≤x+y+z.)
